Description
Technical field
The utility model belongs to building structure technology field, and in particular to a kind of concrete filled steel tube with ribbing surrendered stage by stage
Composite column structure.
Background technology
Steel core concrete column is a kind of new and effective combined member developed in recent years, and it is by steel pipe and steel pipe
Coagulation local soil type into.By the performance of compound action, concrete filled steel tube can give full play to the material of both steel and concrete
Performance.Due to the effect of pipe inner concrete, the stability of steel pipe wallboard is greatly improved, and avoids or has delayed steel plate wallboard mistake
It is early that local buckling occurs.Further, since effect of contraction of the steel pipe to concrete, the compression strength and deformability of concrete obtain
Significantly improve.Steel pipe is also used as the template of concreting, so as to greatly shorten the duration.Due to above-mentioned advantage, steel pipe mixes
Solidifying earth pillar has obtained more and more extensive application in Practical Project.For steel core concrete column, in other conditions identical feelings
Under condition, steel yield strength is higher, and the effect of contraction of steel pipe is stronger, and the bearing capacity of post is higher.Therefore in bearing capacity identical feelings
Under condition, the sectional dimension of steel core concrete column, saving steel can be reduced using high strength steel pipe.But in high strength steel pipe concrete
While post reduces sectional dimension, its rigidity of structure also accordingly reduces, and makes deformation more difficult satisfaction of the structure under small shake effect will
Ask.And common steel tube is compared, high strength steel pipe is more easy to that local buckling occurs before yield strength is reached, strong so as to constrain steel pipe
The performance of degree.

The gross area 1/3~1/2.
It is further preferred that the cross section of the steel pipe is rectangle.
It is further preferred that the cross section of the steel pipe is circle.
The beneficial effects of the utility model：The concrete filled steel tube coupled column with ribbing of the present utility model surrendered stage by stage
Longitudinal floor of low-yield is additionally arranged in steel pipe.Low-yield longitudinal direction floor enhances the local stability of steel pipe, meanwhile, it is low
Yield point longitudinal direction floor can be surrendered prior to high strength steel pipe, consume the energy of Seismic input structure, prevent high strength steel pipe from making in big shake
Premature harm and destruction under, compensate for the deficiency of common concrete filled steel tubular column, have in skyscraper wide
Application prospect.
